Active Directory Management Tool. Microsoft's Group Policy Management Console (GPMC) easily conquered a crowded field for our Best Active Directory Management Tool award, strolling into first place with more than twice as many votes as the second-place finisher. In addition to managing sites, organizational units (OUs), domains, and forests, GPMC helps you implement security settings and distribute software. For copying, importing, backing up, restoring, migrating, reporting on, and delegating management of Group Policy Objects (GPOs), GPMC can't be beat. Scripters in particular appreciate the fact that all GPMC functions can be scripted.
